The unit offers rapid diagnostic breast imaging both full field digital mammography and ultrasound. The different ways of examining the breast are outlined below.
Full field digital mammography is a diagnostic, low dose x-ray examination, using dedicated equipment, for examining the breast. It is usually offered to women over 40 (or 35 with a strong family history and referred by a clinician) and is used routinely in screening programmes. It is also the first investigation for symptomatic purposes, including for those with a family history of breast cancer or on hormone replacement therapy. In order to perform a mammogram, the breast is compressed between two perspex x-ray plates, some women find this uncomfortable, and a very small number may find it painful. Mammography is carried out by a radiographer and the image of the breast is then reviewed by a consultant breast radiologist, who will produce a report for the consultant breast surgeon.

Ultrasound is used where there is an abnormality in a part of the breast and will differentiate solid lesions from cystic ones. Increasingly this technique is used in conjunction with mammography, as both techniques give complementary information. In patients under 35, ultrasound is the usual diagnostic investigation used in conjunction with clinical examination as a screening technique. It uses high frequency sound waves to produce pictures of internal tissues and organs. A special gel is spread onto the breasts and a traducer, a small hand held microphone, which emits sound waves, is passed over the area. The echoes are converted into an image of the breast tissue, which is then reviewed by a consultant radiologist, who will produce a report for the consultant breast surgeon. Ultrasound scans are painless. Ultrasound can also be used by a consultant radiologist to guide the needle to the area of abnormality to have cells taken for fine needle aspiration cytology.
In order to establish a tissue diagnosis, a slightly thicker needle than for FNAC is inserted into the breast, to remove a small tissue sample for histological examination. Local anaesthetic is used to make the area numb before the biopsy is taken. A small cut is then made in the breast and the core biopsy needle inserted to take samples. It can be performed clinically, by feeling the position of the lump, or if the area is very small or cannot be felt, this test can be performed using ultrasound or x-ray guidance (Stereotactic core biopsy). The tissue is sent away for examination (histopathology) and the results are usually available within 48-72 hours. In certain circumstances it renders surgical excision unnecessary if the lesion is confirmed as benign. It may be carried out by either a consultant breast surgeon or consultant radiologist.
Should surgery, for an impalpable abnormality, be required, guidance is provided, for the consultant breast surgeon, using either wire placement or ultrasound guided skin marking, whichever is most appropriate.
